debugdirstate: deprecate --nodates in favor of --no-dates
We have supported 'no-' prefixes for boolean flag for a few years now,
so I was expecting it to be --no-dates.
I noticed that we have --nodates options for a few more commands
(e.g. `hg diff`), but I'll leave that for another day.

#require execbit
$ hg init
$ echo a > a

adding a

Make sure we notice the change of mode if the cached size == -1:
$ hg rm a
$ hg revert -r 0 a
$ hg debugstate
n 0 -1 unset a
$ hg status
M a
$ hg up 0

$ test -x a && echo executable -- bad || echo not executable -- good
not executable -- good
